GALE-WHEEL AND GUDGEON.

Specification of Letters Patent.

Patented May 5, 191 i.

Application filed November 12, 1912. Serial No. 730,953.

To all whom it may concern:

Be it known that I, WILLIAM Knox, a citizen of the United States, residing at Coalinga, in the county of Fresno and State of California, have invented new and useful Improvements in Calf-Vheels and Grid geons, of which the following is a specification.

For diverse reasons it is desirable to vary the diameter of the shaft of a bull or calf wheel according to the particular nature of the work and conditions appertaining thereto. It is also advantageous to make provision for lengthening the rope or cable which cooperates with the bull or calf wheel.

The present invention provides novel means whereby a shaft of given diameter may have its diameter increased to any required extent, the part fitted to the shaft forming for all practical purposes a part thereof and being capable of withstanding tures, details of construction and combination of parts, whlch hereinafter Wlll be more particularly set forth, illustrated in the accompanying drawing, and pointed out in the appended claim.

Referring to the drawing, forming a part of the specification, Figure l is a view in elevation of a calf wheel and gudgeon embodying the invention, a portion being broken away to show the shaft and the sleeve or shell fitted thereon. Fig. 2 is a central longitudinal section of an end portion of the shaft and gudgeon having a sleeve or shell of larger diameter fitted upon the shaft with an interposed filling, the parts being on a larger scale. Fig. 3 is an end view of the gudgeon having the slot in the inner flange through which the rope or cable passes from the drum to the shaft.

Corresponding and like parts are referred to in the following description, and incli- Gudgeons are fitted to the end portions of the shaft 1. The gudgeon shown at the left hand end of the shaft comprises elements 2 and 3 of different diameters, the part 3 being hollow and of an internal diameter to receive an end portion of the shaft 1 upon which it is secured in any convenient and substantial way. The part 2 forms the journal or gudgeon proper and is of considerably less diameter than the part 3. Flanges 4 and 5 are formed with the part 3 and are spaced apart and result in the provision of a drum upon which an extra amount of rope or cable is adapted to be wound, thereby admitting of varying the working length of such rope or cable. A slot 6 is formed in the flange 5 and provides a passage for the rope or cable from the drum to the shaft. The end of the rope or cable is adapted to be secured to the gudgeon in any manner and after the desired amount has been wound upon the drum such rope or cable is passed through the slot 6 and the remainder wound upon the shaft or main part of the wheel.

Should it become necessary from any cause to increase the diameter of the shaft a sleeve or shell 7 having the required external diameter is slipped upon the shaft 1 and may be shrunk thereon or secured thereto in any manner. When the increased diameter is comparatively small the shell or sleeve 7 may consist of a single thickness, the inner diameter corresponding to the external diameter of the shaft 1 to admit of the sleeve or shell slipping upon the shaft. This is indicated most clearly in Fig. 1. However, should the increased diameter be of such an extent as to render it practically impossible or advantageous to use a sleeve or shell of a single thickness and having an inner diam eter to correspond with the outer diameter of the shaft the intervening space between the sleeve or shell and the shaft is filled with cement or other material, as indicated at S in Fig. 2, such filling serving as a bond between the sleeve or shell and the shaft and also as a backing to enable the sleeve to withstand the strain of the rope or cable.

' In this way the diameter of the shaft 1 may be increased to any extent, the sleeve or shell being slipped thereon and the space between the sleeve and shell filled with suitable material. The outer surface of the sleeve or shell is formed with a spiral groove 9 which constitutes a seat to receive the winds of the rope or cable, whereby the latter is caused to wind smoothly about the shaft without requiring guides or other means to cause the winds to lie side by side. From the foregoing, taken in connection with the accompanying drawing, it will be understood that the invention provides an article of the character herein stated which readily admits of the diameter of the shaft being varied and which enables an additional amount of rope or cable to be conveniently carried to allow for increasing the working length of such rope or cable to meet various conditions and requirements, said extra amount of rope or cable being carried in a manner so as not to interfere with the operation of the device or the working lei'igth of the rope or cable.

From the foregoing description, taken in connection with the accompanying drawing, th advantages of the construction and of the method of operation will'be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claim appended hereto.

Having thus described the invention what is claimed as new, is

In combination a hollow shaft, a gudgeon comprising a ournal, body and spaced flanges, the body being slipped upon the end of the shaft and secured thereto, and a sleeve mounted upon the shaft and abutting against the flange at the inner end of th gudgeon and serving as a reel section.

In testimony whereof I ailix my signature in presence of two witnesses.
